SPECIFICATION forming part of Letters Patent No. 350,555, dated October 12, 1886.

To all whom it may concern: 7

Be it known that I, FRANKLIN PHILLIPs, a citizen of the United States, residing at Newark, Essex county, New Jersey, have invented 5 certain new and useful Improvements in Table- Gushioning Devices, fully described and. represented in the following specification and the accompanying drawings, forming a part of the same. This invention relates to an improved means for arresting the movement of a reciprocating table by a yielding cushion; and it consists, essentially, in the combination, with the reciprocating table and a cushion device, of a disk I rotated by the rack of the table and movable to and from the cushion, and clutch mechanism for arresting the rotation of the disk and giving it a movement of translation toward the cushion. Such disk is shown herein as a toothed wheel adapted to mesh with the rack of teeth often used for transmitting a reciprocating movement to a planer-table; but the toothed disk is in such case merely an element rotated by the longitudinal movement of such 2 5 table, and the means for rotatingit are immaterial, provided it be actuatedby the table, as hereinafter described. I

It also consists in means for connecting the table adj ustably at different points in its stroke 0 as by movable dogswith' the clutch mechanism, so as to bring the cushion into action at either end of the variable stroke.

The cushion may be made by a combination of springs, or by a double-acting air-cylinder 5 being constructed, if required, to cushion the movement of the table in opposite directions. The drawings show my invention applied to the bed and table of an iron-planing machine, where heavy weights are traversed back and 0 forth beneath a tool, and Where the momentum of the moving parts commonly exerts a very injurious effect upon the mechanism employed to reverse the movement of the table. In such machines the stroke of the table is variable to suit the length of the work; but none of the reversing devices or mechanism for sustaining the cutting-tool are shown herein, as they form no part of my present invention.

Figure 1 is an end view of the bed and table as shown in Fig. 2 with my improvements 'attached. Fig. 2 is a side view of the bed and table, each being broken off at its opposite ends, where it would be otherwise extended in an iron-planing machine. Fig. 3 is a plan of the parts with table removed shown in Figs. l and 2. Fig. 4is' an enlarged View of the disk, the carriage, and a double-aeting air-cushion cylinder, the cylinder being cut otl to show the air-passages, and one side of thecarriage being removed to show the slotted collar and 6 segment more clearly. Fig. 5 is a plan of the same parts, the carriage being shown in section; and Fig. 6 is a view of the inner end of the clutch-hub.

A is the planerbed; B, the reciprocating ta- 6 ble; 0, the rack ordinarily used for propelling it; D, a rotating disk provided with teeth to mesh with the rack;E, a carriage mounted upon a slide, F, beneath the rack, and sustaining the diskupon a fixed stud, G, the head of c the latter being provided with a key, as at g, to hold it firmly from rotation.

H is an air-cushion cylinder, and I its piston, and J a rod connecting the latter with the carriage. 7 5

a1saclutch-hub,fitted by means of a feather, b, upon the stud G, and provided with teeth a, to mesh with teeth 0, formed upon the face of the toothed disk D.

m is a loose collar applied outside of the s clutch-hub and teeth 0, and provided with an inclined slot, 0, fitted to embrace a pin, gl, which is projected from the hub a. The collar is provided with teeth m, adapted to fit-a segment,

a, which is pivoted upon the carriage E, adja- 8 cent to the collar, and provided with an arm, f, to receive a vibratory motion from the table B. The toothed disk D being constructed to turn loosely upon the stud G, it is obvious that unless it is engaged with the clutch-hub a its 0 rotations would produceno movement of the carriage E. The clutch-hub, being feathered upon the fixed stud G, immediately arrests the rotation of the disk when said stud G is moved longitudinally, so that its teeth a engage with 9 5 those at 0 upon the face of the toothed disk, and such movement of the clutch therefore operates to lock the disk rigidly to the stud upon the carriage E. When thus locked, the

motion of the table is imparted to the carriage roo and to the cushionpiston I, and the cushion thus becomes effective in checking the motion of the carriage.

The means for actuating the clutch at variable points in the stroke of thetable are shown herein as dogs 71. h, bolted to the edge of the table, and operating upon opposite inclines, a, formed at the end of aweighted lever, K. The lever K is connected with the segment a by links 0 0 and cranlcarms o, and the weight L serves to hold the clutch-hub a normally away from the disk D, as shown in Fig. 5. The construction therefore permits the toothed disk to rotate idly upon its supporting-stud until the dogs actuate the segment a, and thus move the clutch-hub toward the toothed disk and lock itto the carriage, when, the carriage being dragged thereafter in the direction in which the table happens to be moving, the cushion is brought into operation and quietly arrests the movement of the table.

In the construction shown herein a doubleaet-ing eusl'iion-cylinderis shown, with the piston I standing at the center thereof over airinlets 1-, to supply air to the opposite ends of the cylinder when the piston is moved therefrom. Each end of the cylinder is provided with a vent-cock, s, which affords an outlet for the confined air, and a means for regulating the force of the cushion.

Springs compressed by the carriage E may be used instead of an air-cushion, and it is also immaterial what means he used to arrest the rotations or to actuate the clutch adjustabl y by the table if a clutch be used.

It will be seen that the sliding carriage sustains the cl nteh mechanism,which is thus movable in relation to the cranks 0, which actuate the segment 02,- butthe link 0 fully compensates for such construction.

I do not claim herein the combination, with a reciprocatingtable, of reversing-dogs and a cushion device actuated directly by the dogs,

clutch between the reversing-dog and the cushion device.

Having thus set forth my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination, with thetable, ofa yielding cushion, asliding carriage for operating the same, a disk adapted to rotate upon the said carriage, means connected with. the table for rotating the disk, and a clutch upon the carriage for arresting the rotations of the disk, as and for the purpose set forth.

2. The combination, with the table, of ayielding cushion, a sliding carriage for operating the same, a disk adapted to rotate upon the said carriage, means connected with the table for rotating the disk, a clutch for arresting therotations of the disk, and a cl utclrshifter actuated by the table at given points in its stroke, as and for the purpose set forth.

3. The combination, with the table, 0 fa yielding cushion, a sliding carriage for operating the same, a disk adapted to rotate upon the said carriage, means connected with the table for rotating the disk, clutch mechanism movable with the carriage for arresting the rotations of the disk, one or more adjustable dogs upon the table, and means operated by the dogs for actuating the clutch, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
